Sexual dysfunction and its determinants in women with rheumatoid arthritis.

OBJECTIVES

To evaluate sexual function in Tunisian women with rheumatoid arthritis (RA) and to examine factors that are predictors of female sexual dysfunction including sociocultural factors, disease activity, and psychological status.

METHODS

We conducted a cross-sectional study including 71 women with a confirmed diagnosis of RA according to the 2010 American College of Rheumatology/European League against Rheumatism (ACR/EULAR) criteria. Clinical and sociodemographic characteristics were collected. The participants were asked to complete the Female Sexual Function Index (FSFI), which contains 19 questions, assessing six areas of female sexual function in the previous 4 weeks. Sexual dysfunction was defined as an FSFI score less than or equal to 26.55. The psychosocial status was evaluated by the Hospital Anxiety and Depression (HAD) scale. Prevalence of sexual dysfunction and predictors of sexual difficulties were assessed.

RESULTS

The prevalence of female sexual dysfunction in women with RA was 49.3%. All areas were altered especially desire (2.92 ± 1.3), arousal (3.27 ± 1.5), and orgasm (3.77 ± 1.5). In univariate analysis, sexual dysfunction was correlated with the age of patients (p = 0.049), the age of partners (p = 0.013), pain (p = 0.001), number of night awakenings (p = 0.02), morning stiffness (p = 0.010), tender joints (p = 0.05), disease activity score (DAS28 ESR) (p = 0.043), fatigue (p = 0.028), and Health assessment questionnaire (HAQ) (p = 0.02). In multivariate analysis, the age of patients and pain were predictive factors of sexual dysfunction. By analyzing each area of the FSFI score, the age of patients was the independent variable associated with desire. Tender joints were associated with lubrication and the age of partners with arousal, orgasm, and satisfaction.

CONCLUSION

Our study suggests that rheumatoid arthritis has a negative impact on patients' sexuality. Age of patients and partners, pain, and tender joints appear to be the main factors influencing sexual function.
